AI stocks surge as Super Micro posts $18.5‑$19.5 bn sales, beating forecasts

Shares of AI‑focused companies jumped in after‑hours trading on Tuesday after Super Micro Computer Inc. reported quarterly sales of $18.5‑$19.5 billion, well above the roughly $15 billion analysts had expected. Dell Technologies Inc. and Hewlett Packard Enterprise Co. each rose more than 5%, while neocloud providers CoreWeave Inc. and Nebius Group climbed over 4%. The VanEck Semiconductor ETF added 2.2% and the Invesco QQQ Trust, which tracks the Nasdaq‑100, gained as much as 0.9%.

Market Reaction

The rally came amid a broader slowdown in the AI trade this month, where worries about unsustainable spending on computing infrastructure have pressed prices. The Philadelphia Stock Exchange Semiconductor Index slipped 11% in October, setting up its worst month since July. Companies that rent AI‑compute capacity, such as CoreWeave, have felt the pressure; CoreWeave’s shares were down 29% for the month, and the firm is financing its build‑out by issuing bonds. Rising Treasury yields have also lifted debt costs for firms relying on borrowing to fund AI projects.

Background

Super Micro’s upbeat guidance lifted sentiment, and the news coincided with a strong earnings report from Elon Musk’s SpaceX. SpaceX beat revenue and profit forecasts, driven by growth in its AI and satellite‑internet divisions, and its stock rose 5.6%.

Context

A higher‑than‑expected sales figure from a key server supplier signals that demand for AI hardware may still be robust despite recent market jitters. The mixed performance of related stocks shows investors are weighing individual company results against overall sector concerns.
